[quote name='SpazX'] On a semi-related note, for the XBLA games that don't have a save file, but clearly had to save something (splosion man, arkadian warriors, etc.), is that in my profile or in the game file itself?[/QUOTE]
Its in your profile.
For above questions about file transfer kits - I just bought a large memory stick at BB and transfered all my saved game and profiles in 2 tries, if you played a lot of games it might take a couple more tries - then I just returned the memory stick and got all my money back.
It was the quickest and a free way to get this done, without paying MS 12 bucks and waiting 2 weeks for the official kit.
Hope that helps.
